Title: Clutch disc with friction damping
Inventor: PRETZEL DIETER
IPC: F16F15/129
Filed: 1996-02-23
Abstract: The invention relates to a damping device with at least two component parts 9, 11 rotatable relative to each other about a rotary axis. A friction device 6 is provided between the parts and has an annular friction part 15 and an annular spring element 16 which undulates around its circumference.

Patent GB-2297194-A (GB)
Title: Improvements in/or relating to electrical switches
Inventor: COOK DAVID LANGMAN
IPC: H01H23/06
Filed: 1995-08-30
Abstract: The present invention consists of an electrical switch with a mounting plate in which is pivotally mounted a switch rocker that has a dependent control member co-operatively engaged with an actuator in a switch unit so that operation of the switch rocker will transmit movement to the switch actuator to provide the switching action in the switch unit. This construction has particular advantages where the switch is to be used in conditions requiring waterproofing because a diaphragm can be fitted between the switch unit and the switch rocker with the control member extending through an aperture in the diaphragm while maintaining a sealing fit between the control member and the diaphragm. The diaphragm is preferably shaped and fitted so that is contacts the control member of the switch rocker at or adjacent the pivot line of the switch rocker thus minimising movement of the diaphragm upon operation of the switch rocker. The invention also allows different dimensions of switch rocker to be applied where, for example, a switch may be required to provide a larger operating surface, for example, for handicapped or disabled users. <IMAGE>

Title: Transmission of measurement reports from a mobile station to a base station and a service node in a cellular communication system
Inventor: REYNOLDS PAUL
IPC: H04W36/00
Filed: 1997-12-12
Abstract: In a cellular communication system a mobile station 8 performs radio link measurements for the serving and neighbouring cells and transmits radio link measurement reports to a serving base station controller (BSC) 4 so that the serving BSC can make handover decisions. The mobile station also transmits radio link measurement reports to a service node 108 in encapsulated form, eg in the form of short message service (SMS) messages in order to prevent the interception of the measurement report by the serving BSC. The service node makes handover decisions using the reports and parameters stored in a database. The parameters include a list of target nodes, personal subscriber profiles and service information including bandwidth requirements, quality of service requirements, access rights, priority and preference lists, congestion and load control related parameters etc. Handover decisions can be made at the service node instead of or additional to the normal handover decisions made at the BSC.

Patent GB-2337632-A (GB)
Title: Ion beam apparatus and a method for neutralising space charge in an ion beam
Inventor: ENGLAND JONATHAN GERALD
IPC: H01J37/317
Filed: 1998-05-12
Abstract: A source of thermionic electrons 5 is provided inside the flight tube 2 of a magnet 1, especially an analysing magnet, and extends along the beam flight path. This allows space charge to be neutralised along the beams axis in spite of severely restricted electron mobility in this direction owing to the presence of substantially transverse magnetic field B. Thermionically emitted electrons may contribute directly to the neutralisation of space charge in positive ion beams, or, in the case of negative ion beams, indirectly by ionizing residual or deliberately introduced neutral gas atoms or molecules. Examples are described in which the source is arranged outside the nominal beam envelope in the flight tube, but linked to the beam by magnetic flux generated in the flight tube. This reduces erosion of the source by the beam and so reduces beam contamination. In these examples, an important feature is the provision of electron repellers to reflect electrons back and forth across the beam. Alternative arrangements are described in which the source is positioned inside the beam. The thermionic electron source may comprise one or an array of filaments, and preferably is negatively biased with respect to the flight tube. Adjustment of this bias enables the energy of emitted electrons to be controlled. The filament(s) may be made of graphite, tungsten or another metal.

Title: Puncturing and recovering code in a spread spectrum communication system
Inventor: PARK SU-WON
IPC: H04B1/69
Filed: 1998-07-30
Abstract: Device and method for puncturing and recovering a code in a spread spectrum communication system. Repeated symbols are punctured in predetermined locations and different data is inserted in the punctured locations in a transmitter. Then, the punctured symbols are recovered by separating the inserted data from input data and filling previous unpunctured symbols in the punctured locations in a receiver. In another embodiment, the transmitter simply punctures repeated symbols in predetermined locations to obtain an intended symbol rate. Then, the receiver recovers the punctured symbols by filling previous unpunctured symbols in the punctured locations. Therefore, errors at channel decoding can be reduced.

Title: Semiconductor wafer fabrication of inside-wrapped contacts for electronic devices
Inventor: RICHARDS JOHN G
IPC: H01L23/485
Filed: 1998-01-26
Abstract: A packaging technique for electronic devices includes wafer fabrication of contacts that wrap down the inside surface of a substrate post. Inherently reliable contacts suitable for a variety of devices can be formed, via a simple fabrication process, with good wafer packaging density. A trench (303) is formed in the top surface of a substrate (300) parallel to the edge of its electronic circuit. A gold beam wire (305) extends from a connection point within the circuit into the trench (303). Unless an insulative substrate is used, the wire (305) runs over an insulating layer that ends part way through the trench (303). After epoxy encapsulating (306) the top of the substrate (300), it is back planned to form the bottom surface of the post (313). Then it is selectively back etched, to expose the bottom surface of the wire (305), to form the inside surface of the post (313), and to form the bottom surface of the finished device. A solderable lead wire (307) runs from the exposed gold wire (305), down the inside surface of the post, and across its bottom. Sawing forms the outside surface of the post and completes the finished device without subsequent assembly. Alternatively, no post is used and the contact compromises an encapsulant protrusion, similarly formed in a silicon trench that is subsequently etched away. Gold wires run under the protrusion and may be covered by solderable metal, or a dense gold compression bond may be used. Optionally, the bottom of the finished device drops down to be co-planar with the contact bottoms, so as to conduct heat out of the device.
